Latest / The Side Hustle Career Podcast with Fexingo: Second Income, Freelancing While Employed / How a Bank Teller Built a 20K Side Hustle in Fractional Bookkeeping
Transcript
- Lucas: So Luna, there's a story I keep coming back to this week — a bank teller who built a twenty-thousand-dollar-a-month side hustle in fractional bookkeeping. Luna: Twenty grand a month? That's not a side hustle, that's a second full-time income. Lucas: Exactly. And the wild part is she didn't come from an accounting background. She was a teller at a regional bank in Ohio, handling deposits and withdrawals all day, and she noticed something. The small business owners who came in — the coffee shop owners, the plumbers, the online sellers — they were constantly stressed about their books. Not because they were bad with money, but because they didn't have time to track every transaction, categorize expenses, and reconcile accounts. Luna: So she basically saw the pain point from the other side of the teller window. Lucas: Exactly. She started helping one or two of those customers on the side, just doing their books in the evenings using QuickBooks. She charged fifty dollars an hour at first. Within a year, she had twelve clients, mostly e-commerce brands that needed monthly reconciliation, sales tax tracking, and profit and loss statements. She raised her rates to a hundred and fifty an hour, and now she's clearing twenty grand a month consistently. Luna: So the key wasn't just 'learn bookkeeping' — it was targeting a specific niche where the demand was hot. E-commerce. Lucas: Right. And that's the angle I want to dig into today. Because fractional bookkeeping is one of those side hustles that seems boring on the surface, but it's actually perfect for anyone who's comfortable with numbers, detail-oriented, and willing to learn a few software tools. And the e-commerce niche specifically is exploding. Luna: Why e-commerce, though? I'd think local service businesses would be easier to land. Lucas: You'd think so, but here's the thing — e-commerce businesses have a paper trail that's almost entirely digital. Sales through Shopify, expenses through Stripe and PayPal, inventory through inventory apps. It's messy, but it's also automatable. And because sellers are often doing everything themselves, they're willing to pay for someone who can just make the books clean. Plus, they're used to paying monthly subscriptions, so a recurring retainer feels normal. Luna: So she's not doing hourly billing anymore, she's doing monthly retainers. Lucas: Exactly. She moved to a flat monthly fee — two hundred and fifty dollars a month for basic bookkeeping, five hundred for a more complex setup with inventory or multiple sales channels. With twelve clients at an average of four hundred dollars a month, that's nearly five grand a month. But she also does quarterly catch-up work and tax prep for some clients, which pushes her to twenty. Luna: And she's still working at the bank? That's a lot on top of a forty-hour-week job. Lucas: She does. But here's the smart part — she's using her bank job for health insurance and a steady base salary, and she's capped her side hustle at about fifteen hours a week. She's very disciplined about it. She batches her client work on Tuesday and Thursday evenings, and she uses automation tools to handle the repetitive stuff. She told me she spends maybe two hours a week on data entry now, because she's set up bank feeds and rules in QuickBooks that categorize transactions automatically. Luna: So the real skill isn't data entry, it's setting up systems that do the data entry for you. Lucas: Bingo. And that's a lesson that applies way beyond bookkeeping. Whether you're freelancing as a writer, a designer, or a consultant, the people who make serious money on the side are the ones who build systems, not just do the work. They automate the boring parts so they can focus on the high-value stuff — talking to clients, analyzing the numbers, making recommendations. Luna: And speaking of talking to clients — how did she land her first few? She wasn't exactly networking on LinkedIn from the teller window. Lucas: She actually started by talking to the small business owners who came into her branch. She'd ask them how their books were going, and if they mentioned being behind, she'd offer to help on the side. That's how she got her first three clients — all local, all people she already had a relationship with. Then those clients referred her to other e-commerce folks they knew. She didn't do any cold outreach until she was already at eight clients. Luna: So she used her existing network and her credibility as a bank employee. That's a smart way to start — no cold calling, just warm conversations. Lucas: And she was careful about compliance. She checked her bank's policy on outside work, and she made sure she wasn't using any bank resources or client data. That's actually a really important point for anyone in a financial role who wants to side hustle — you have to be clear about conflicts of interest and confidentiality. Luna: Yeah, that's a good caution. I'd hate to see someone lose their day job over a side hustle. Lucas: So let's talk about the numbers a bit more. She charges an average of four hundred dollars a month per client. Now, that might sound like a lot for bookkeeping, but when you break it down, it's about ten hours of work per client per month at her effective hourly rate. She's basically selling her time at forty dollars an hour, which is decent for a side hustle, but the real money comes from scale and from the higher-tier clients. Luna: So the key is to keep raising rates as you get more experience and more referrals. Lucas: Exactly. She started at fifty dollars an hour, then moved to a hundred and fifty. And she's not shy about raising rates for new clients — she actually tells every new client that her rate will go up after the first year. That's a standard practice in consulting, but a lot of freelancers don't do it. They're scared of losing clients. But if you deliver real value, clients will pay. Luna: What about the tools? You mentioned QuickBooks and Shopify — what else does she use? Lucas: She uses QuickBooks Online as her main accounting software, and she connects it directly to the client's Shopify store, Stripe account, and PayPal. She also uses a tool called Hubdoc to automatically pull in receipts and invoices, which saves her a ton of time. And for sales tax, she uses Avalara, which integrates with most e-commerce platforms and files sales tax returns automatically in multiple states. Luna: So she's basically become a mini cfo for these small businesses. They get the same kind of financial reporting that a big company would have, but at a fraction of the cost. Lucas: That's exactly the pitch. And that's why she's been able to grow. She's not just doing data entry — she's giving them monthly P&L statements, cash flow projections, and profit analysis by product line. That's the kind of insight that helps them make better business decisions, and it's worth way more than a few hundred bucks a month. Luna: So what's the downside? I mean, fifteen hours a week on top of a full-time job sounds exhausting. Lucas: It is. She told me the biggest risk is burnout. She's been doing it for two years now, and she's had to be really strict about her schedule. She doesn't check client emails on weekends, and she takes one full week off every quarter. She also says that the best thing she did was to set up systems early so that she's not doing the same manual work over and over. Luna: So the systems aren't just about making money — they're about protecting her time and her sanity. Lucas: Exactly. And I think that's a lesson for any side hustle. If you're spending hours on the same repetitive task, you're not building a business, you're just creating a second job. The goal is to create something that can eventually be scaled down on your time or even sold. Luna: Have you seen any other examples of that with your listeners? I remember we talked about the librarian who built a metadata consulting business — she had a similar approach to systematizing her work. Lucas: Yeah, absolutely. That librarian built checklists and templates that she could reuse across clients, and she eventually hired a virtual assistant to handle the admin. Same principle — build it once, then scale it. Luna: So if someone's listening right now and thinking 'I could do this' — what's their first step? Where do they start? Lucas: First, you need to learn the basics of bookkeeping. You don't need a degree, but you do need to understand debits and credits, how to reconcile a bank account, and how to read a profit and loss statement. There are tons of free resources online — QuickBooks has a certification program, and there are courses on Udemy and Coursera for under fifty bucks. Luna: And then you need to get your first client, even if it's for a low rate, just to get experience. Lucas: Right. Start with someone you know — a friend who runs a small online store, a family member who has a rental property, maybe even a local non-profit. Offer to do their books for a few months for free or at a steep discount, just to build a portfolio and get testimonials. Once you have two or three happy clients, you can start charging real rates. Luna: That's a solid plan. And honestly, the e-commerce niche is so deep that you could even specialize further — like bookkeeping for Etsy sellers, or for supplement brands, or for businesses on Amazon FBA. Lucas: Exactly. Niching down is the fastest way to command higher rates. If you're just a 'bookkeeper', you're competing with everyone on Fiverr. But if you're the bookkeeper who specializes in Shopify stores selling physical products, you become the go-to person for that specific problem. And you can charge a premium. Luna: And with the rise of e-commerce — I mean, online sales are still growing steadily in 2026 — there's no shortage of demand. Lucas: Right. And that's why I think this story is so compelling. It's not about some tech genius creating an app. It's about a bank teller using her existing skills, learning a few software tools, and building a service business that she can run from her kitchen table in the evenings. It's realistic and it's replicable. Luna: Speaking of kitchen table — we should mention that this show is only possible because of listeners like you. If you've gotten value from these episodes, a handful of you already chip in monthly through buy me a coffee dot com slash fexingo, and that's what keeps the podcast ad-free and independent. Lucas: Yeah, it's a small group, but it genuinely makes a difference. No pressure, obviously — it's just how we keep doing this without sponsors. So if you're able, you know where to find us. Luna: Okay, back to bookkeeping — you mentioned that she uses Avalara for sales tax. That's a bit more advanced, right? Do beginners need to worry about that? Lucas: Not right away. When you're starting out, you can just use QuickBooks' built-in sales tax features. But once you have clients selling in multiple states, it becomes a nightmare to file manually. That's when tools like Avalara or TaxJar pay for themselves. Your clients will happily cover that cost because it saves them hours and avoids penalties. Luna: So the takeaway is: start simple, learn the basics, find a niche, and build systems that scale. Lucas: That's the whole episode in a nutshell. And if you're sitting there thinking 'I'm a bank teller' or 'I work in retail' or 'I'm a receptionist' — you probably have more transferable skills than you realize. The key is to find a service people will pay for, and then build a mini-business around it.
